PHIN EAS F. KING, OF SI. LOUIS, ASSIGNOR TO HIMSELF AND ALFRED S. WOLF, OF KANSAS CITY, MISSOURI.

NAILWEXTRACTOR.

SPECIFICATION forming part of Letters Patent No. 313,599, dated March 10. 1335- Application led December 30, 1884.

To all whom, t may concern.-

Be it known that I, PHiNnAs F. KING, a citizen of the United States, residing at St. Louis, and State of Missouri, have invented a new and useful Improved Nail-Extractor, of which the following is a specification.

My invention relates to the class of nailextractors; and it consists of an improved instrument, implement, or tool, in the use whereof the extraction of nails, spikes, and fastenings of a similar nature can be accomplished in the most quick, decisive, and noisless manner without injury to the nails or fastenings, and which, further, as a tool shall possess the advantages of being simple, cheap, and durable, and in its operation most effective and reliable. I attain these objects by the mechanism illustrated in the accompanying drawings, inwhich- Figure l is a perspective view of the entire tool. Figs. 2, 3, 4 are views designed to illustrate the successive positions or movements the tool is made to assume during the operation ofwithdrawing the nail. Thus Fig. 2 represents the tool as applied in position preparatory by its claws to nip or grasp the nail. In this position the claws and fulcrum-plate are in their highest position. Fig. 3 shows the tool in the position it assumes when its claws have been drawn completely under the head ofthe nail. In this position the claws and fulcrum-plate are in their lowest position. Fig. et represents the tool in the final position it assumes to extract the nail; and Fig. 5 is a plan View taken on line 5 5 of Fig. 3.

Similar letters refer to similar parts throughout the several views.

A is the hand-lever. This at its lower end has the crook or curved offset at A, terminating in claws at B,in manner indicated in Figs. l, 2, 3, 4. Between the claws exists the open space b, which permits the claws to be drawn under the nail to grasp its head and retain the nail between the jaws. This open space is wider at the front than the rear, (see Figs. l, 5,)to adapt the claws to take hold of differ ent sizes of nails. Also, the outer faces at b b2 of the claws I make a taper or to bevel, as shown in Figs. l, 2, which taper facilitates the claws entering under the head of the nail,

(No model.)

and at same time to crease or cut the surface as slightly as possible; also, the claws are tapered when viewed in plan view, (see let ters Z)3 b4 in Figs. l, 2, 5,) by means whereof the claws retain their hold upon the nail dun ing the Various positions the tool is made to assume, as will hereinafter be described.

C is the fulcrum-plate. This has its bearing edge formed with teeth c, to take a better hold and retain a firm bea-ring at that point. The fulcrum-plate C is forked or slotted, so that its two opposite sides at o o2 can be pivoted to the crook of the handhaver. (See Figs. 1 and 5.) For this purposea piu, c3, passes through said parts and virtually hinges said fulcrum-plate to said lever behind its jaws. (See iigures.) At c4 is a shoulder to estop the fulcrunrplate or the hand-lever when turned. A spring, c5, surrounds the pivotal p, end and is interposed between the sides of the fulcrum-plate and crook of the lever. Said spring automatically restores the fulcrumplate to its position.

The parts being thus constructed and arranged, the operation and use of the tool are as follows: In rst applying the tool the operator places saine with relation to the nail or fastening to be extracted as shown in Fig. 2. In this position the hand-lever is forward, its claws and fulcruni-plate are in their highest position, and the nail-head is near the front entrance ofthe claws. The operator next raises the hand-lever to assume the vertical position shown in Fig. 3. This action lowers the claws, also lowers the fulcruni-plate in manner indicated in said figure. Here it will be noted that in the adjustable action of the fulcrumplate the head of the nail or fastening draws the claws under Jthe latter, retaining their hold upon the nail until the fulcruni-platehas been brought to its lowest position. To finally extract the nail or fastening, the operator draws back the hand-lever to the position shown in Fig. 4t, which actionextracts the nail in raising the claws, the lower end ofthe fulcrum-plate serving as the bearing for this lift movement. The bearing of the fulcrumplate at c remains the same during all the positions the tool is made to assume.

My improved tool is noiseless in its operation. It decisively takes hold of the fastening, and by its leverage renders the extraction of the nail or fastening a very simple and easy one.

As apparent, the tool can be made large or small, according to the uses it is to be applied, 'and is therefore adapted for a Wide range of purposes. c

What I claim is* t 1. rlhe combination, With the hand-lever having the crook or offset A', terminating in claws B, the pivoted fulcrum-plate C, and interposed spring e5, substantially as and for the purposes set forth.

Vc5, all combined to operate in the manner and 2o for the purposes set forth.

In testimony of said invention I have hereunto Set my hand.

PHINEAS F. KING.
